WASHING= SPECIFICATION forming part of Letters Patent No. 448,377, datedMarch 1'7, 1891.

Application filed SeptemberlO, 1890. fi'erial No. 364,504. (No model.)

To all whom it may concern:

Be it known that 1, JOHN HENRY SLAcK,a citizen of the United States,residing at Oincinnati, Hamilton county, State of Ohio, have inventedcertain new and useful Improvements in Washing-Machines, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates more particularly to lo that class of washershaving an outer stationary cylinder or casing to contain the water andwashing fluids and an inner rotatable cylinder in which the clothes aredeposited, as will more fully hereinafter appear.

In the accompanying drawings, Figure 1 is a perspective view of myimproved washer as preferably constructed, a portion of the outer andinner cylinders being broken away, showing one of the truss bolts orrods which pass through the corrugated ribs on the inner face of therotatable cylinder to prevent bulging or torsion of the latter when inoperation. Fig. 2 is a vertical cross-section through the innercylinder, the same being removed from the outer stationary cylinder.Fig. 3 is a cross-section on an enlarged scale, taken through a portionof the inner cylinder near its end portion, showing the preferred modeof connecting the perforated embossed sections which go to make up thebody portron of said cylinder, and also the corrugated ribs on the innerface thereof through which the truss-bolts pass. Fig. 4: is a viewsimilar to Fig. 3, taken at or near the center of said cylinder, showingthe boss or lug in said rib over which the truss-bolt passes. Fig. 5 isan lnner face view, on an enlarged scale, of the preferred form ofperforated embossed metal of which the body portion of the innercyllnder is made up. Fig. 6 is a view taken on the reverse side to thatshown in Fig. 5, show- 1ng one mode of forming the embossed portionaround the perforations. Fig. 7 is a crosssection taken through one ofthe embossed perforations shown in preceding figures.

My invention consists more particularly in the formation of the embossedperforations in a sheet of suitable metal of which the inner cylinder ismade up. It will be seen in Figs. 5, 6, and 7 that each perforation issurrounded by a smooth raised or embossed portion,o.r, in other words,perforations within an embossed figure.

My invention also consists in the construction of the inner cylinder,the body portion of which has the inwardly-embossed perforations.

As shown in Fig. 1, and, as already stated, my improved Washing-machineconsists of an outer stationary water-cylinder A and an inner rotatablecylinder 13. The body portion of this inner cylinder is made up ofsheets of suitable material having perforations a therein, eachperforation being surrounded by a raised or embossed portionb on itsinner surface, as more clearly shown in Figs. 5 and 7, the edge orsurface metal forming said embossed perforations being turned inward androunded outward within said perforations, as shown at b, Fig. 7, at ornearly on a plane with the outside surface of said metal, as shown, thusproducing a smooth embossed ring 1) around said perforations on theinner face of the cylinder. hen formed, as shown, the embossed portionl) is struck up integral With the sheet; but it is evident said embossedportions might be formed separate from the sheet and clamped in theperfora tions, as eyelets drc, without departing from my invention. Theperforations (a and their surrounding raised portions may be of anydesired out-line other than that herein shown. The sheets thus embossedand perforated may be secured together cylindrically in any desiredmanner, the mode shown being to overlap the meeting edges of said sheetsand then rivet them together, the rivets passing through one side flangeof the corrugated ribs, which are riveted to the inner face of saidinner cylinder. Having formed the body portion of the perforatedembossed cylinder, it is then secured within the flanged heads D andriveted to the inwardlyprojecting flanges cl of said heads, as shown.The truss-bolts E, which pass through the ribs 0 and through said heads,assist to retain the body portion of the cylinder within the flangedheads.

As shown in Figs. 1 and a, the truss-bolts E pass over a boss or lug f,centrally located within the ribs 0, the object of which is to preventtorsion or bulging of the body portion in operation, the tension oftruss-bolts E on said lngsftending to retain the central portion of saidcylinder in its normal position. The heads of the inner cylinder areprovided with suitablejournals, which restin suitable hearings in theends of the outercasing, as shown in Fig. 1, in which position saidcylinder may be rotated or alternately rotated in opposite directions.Any suitable driving mechanism may be employed for rotating said innercylinder, which latter is provided with a suitable lid.

\Vhile it is preferred to connect the body portion of an inner cylinderthus perforated and embossed within its flanged heads in the mannerdescribed, it is evident that the body portion of a cylinder thusperforated and embossed may be otherwise constructed without departingfrom my invention.

The advantages of my invention are obvious. The perforations permit ofwater passing through the inner cylinder, and the embossed portionssurrounding said perforations prevent catching and tearing off buttonsor rendiug the clothes, and at the same time aitord asuperiorrubbing-surface to more perfectly cleanse the same.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

A washing-machine having an outer stationary cylinder and an innerrotatable cylinder, the body portion of said latter cylinder havingperforations therein, each perforation being surrounded by a smoothembossed or raised portion,the metal forming said embossed portion beingturned inward and rounded outward within said perforation, and suitablemeans for rotating said cylinder, for the purposes set forth.
